Sony VGN-B3VP Power Adapter
Because Sony uses one power charger that can be used on other units, be certain to thoroughly note the part number that is needed for this model. Upon choosing a replacement AC adapter, the actual Sony brand is usually going to be the safest choice. The Sony VGN-B3VP AC adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop. A universal AC adapter can be used if you absolutely need to. If buying off-brand, make note of both the voltage and amperage output.
Important signs the Sony power adapter will have to be replaced
- Battery does not charge up every time
- The unit will not run using just the AC power adapter
- The majority of Sony power chargers can get quite warm when plugged in for any length of time
